Hi Goosey,
Patterns remind me of genus
Zygina, but most of those I know are more "white-ish" with red markings and all quite small (2-3mm) - how big was this one, and was the colour indeed the greenish the image suggests, or is that due to reflections or something?
If indeed greenish
Zygina rubrovittata might be worth looking at
But you know me ... no way that could ever be intended to be a proper ID - just thinking along
